The printer is out of paper 100, and the printer prompts that there is no paper but there is paper

If this happens, it is likely that there is a problem with the printer's paper transmission structure, or it may be that the paper is not properly placed. Normally, there is a photoelectric sensor at the printer paper slot, the photoelectric sensor can keenly "capture" whether the paper is correctly placed in the paper feed slot, if there is printing paper in the paper feed slot, the photoelectric sensor can identify the paper, and generate an identification signal to transmit to the printer, notify the printer to do the printing preparation, even if the paper is not put in the paper feed slot, the photoelectric sensor will also have a control signal transmitted to the printer, tell the printer that there is no printing task temporarily. According to the above feeding principle, it is not difficult for you to know why there is printing paper in the paper feed slot, but the printer prompts that there is no paper; If the photoelectric sensor is covered with dust, it will reduce its ability to recognize the paper, so that even if the paper has been inserted into the paper slot, the photoelectric sensor will not recognize it correctly, so the above strange phenomenon occurs.

In order to avoid this phenomenon, you should pay attention to cleaning the printer at ordinary times, especially the photoelectric sensor. When cleaning the sensor, you should first carefully remove the paper roller from the printer, and then use a fine soft cotton gauze cloth to carefully clean the dust covering the photoelectric sensor, it is worth noting that do not use force during the cleaning process to avoid damaging the photoelectric sensor. (Bend).

It may be that the printer is not installed correctly, it is recommended to check each interface, be sure to plug in tightly, to ensure the correct connection, if the system can not automatically find the printer, but also to install the driver that comes with it, if the above operations are carried out, generally can be printed correctly, if the fault is still the same, please send it for repair in time!

1. The paper is not properly placed.

2. The photoelectric sensor at the paper feed slot of the printer is covered with dust, which reduces its ability to identify the paper. Use a soft cloth to clean the dust covering the photoelectric sensor, and you're done!

The reasons may be: 1. The printer does not move the paper; 2. Printer failure. The workaround is:

1. The printer does not move the paper.

If the paper roller does not roll the paper in, it may be that the wheel is smoothed, or the paper may not be put away. Replace the wheels or readjust the paper prevention position.

2. Printer failure.

You can cancel the print job and then print again; The problem of the general printer can be solved by restarting the printer or restarting the computer, and if necessary, reinstall the printer driver as appropriate.

This answer applies to most printer models.

Here's how to fix it:1. Check whether there is a paper jam in the printer.

If there is a paper jam, go and remove the jammed paper and put it in again to try.

2. There is a problem with the printer driver.

Go and reinstall the printer driver and upgrade the printer program.

3. The paper sensor is polluted.

Follow the instructions to find the printer sensor and see if there is any dust and dirt inside, and if so, remove it.

4. The paper feeding setting and paper feeding specifications of the printer do not meet the requirements.

Check that the paper is set up correctly and set the paper to the paper size.

5. The motherboard of the printer is damaged.

If this situation is not a professional, it will be sent to the designated after-sales store for repair.

It may be that there is a paper jam, if the paper is jammed, you can open the back cover of the printer, and slowly remove the jammed paper after seeing it.

Other Failure Scenarios for the Printer:

1. The cartridge cart is stuck: the cartridge cart is stuck in the printer on the left, unplug the power cord, push the cartridge cart to the leftmost printer, plug in the power cord, turn on the computer, the indicator light is no longer flashing, and then troubleshoot; If the cartridge cart is still stuck, it is recommended to send it to a professional printer repair center for repair; Or find a special printer maintenance personnel to repair and replace ink cartridges.

2. The printer is out of paper: Press the power button of the printer to determine whether the printer is flashing due to lack of paper.

What to do in the face of printer failures.

When there is a problem with the printer, the first thing to do is to use the printer self-test system to detect it, which may be through the printer's own indicator light or buzzer.

The indicator light can indicate the most basic faults, including lack of paper, lack of ink, lack of power, etc.

The judgment of the buzzer mainly depends on your hearing, for example, most printer buzzers use a long beep to indicate that they are ready to print, and a short sound to indicate that the printer is faulty, etc.

Secondly, you can observe the line, starting from the detection of the printer cable (including the detection of ports, channels, and printing lines), and then analyze the internal structure of the printer (including the paper holder, paper inlet, print head, etc.) to see whether the parts are working correctly, lock the relevant parts for different fault conditions, and then determine the parts with problems.

The printer shows that there is no paper, but what to do if there is paper.

Hello, if your printer shows that there is a shortage of paper, but you do have enough paper, then you can try the following methods:1Check that the paper is properly placed in the printer.

Check that the paper is neatly placed in the paper tray. If the paper is not properly aligned, it may warp, causing the paper to be undetectable by the printer. 2.

Check the printer's sensors. There are sensors on the printer's shield that detect the paper, and if there is a problem with the sensor, the printer may not be able to detect the paper. You can refer to the printer manual to check the location and condition of the sensor, and patiently troubleshoot the problem.

3.Check that the printer cartridge or toner is normal. There may be small paper scraps in the ink cartridge or toner, especially after a new cartridge or toner, which can clog the printer sensor and prevent the paper from being detected.

If none of the above methods solve the problem, you can try restarting the printer, and the problem may disappear after restarting.

There could be several reasons for this:

1. Check whether there is a paper jam in the carton or tray.

Solution: If the paper is jammed, take out the paper jammed and try again.

2. The driver is wrong, and sometimes the printer driver is broken.

Solution: You can reinstall the printer driver or upgrade the driver.

3. The printer paper sensor is contaminated.

Solution: You can find the printer sensor according to the instructions and observe if it is contaminated with dust, if it is dust removal.

4. The paper feeding setting of the printer is inconsistent with the paper feeding specifications.

Solution: Check whether the paper settings are correct and set the paper to paper size.

5. The printer motherboard is damaged.

Solution: to the designated after-sales repair.

In our daily work, many people will encounter the situation that when using the printer, there is still paper in the printer's paper slot, but the printer keeps prompting that there is a shortage of paper. Printers

Today, Xiaohua will explain the reasons for this situation and how to solve it.

1. The printer is jammed, resulting in the paper not being able to enter.

At this point we can do this by opening the printer cover.

Check whether there is a paper jam inside the machine and clean up the waste paper can solve the problem.

Second, the paper is not placed in place or the paper size is set incorrectly.

Many novice printers will have this situation, different models of printers adapt to different specifications of printers, pay attention to the selection of the correct specifications of the printer.

In addition, printer paper slots are often designed to be deeper, so novices can try to lower the paper a little deeper until they feel the paper being resisted.

3. The printer paper sensor is out of order.

If there is a foreign object or damage on the sensor, the printer paper will usually not be detected.

We can gently wipe the sensor with alcohol to clean it, if it still doesn't work, consider calling a maintenance master to repair or replace it.

Fourth, the paper roller is worn.

The paper pick-up roller is one of the more susceptible parts of a laser printer to wear and tear.

If the paper in the paper tray is placed normally, but the machine cannot feed the paper, indicating that there is a shortage of paper, it may be because the paper roller is worn or the spring is loose, resulting in insufficient pressure to feed the paper into the machine, in this case, you can seek a professional to overhaul and replace the paper roller.

When the printer is in use, it is not short of paper, but it shows the indication of lack of paper, because the relevant tools have not reached the reasonable degree of closure of the standard, or the bad state caused by the failure of the machine, so it is best to recommend standardized operation, and use it reasonably under the guidance of professionals, so that the effect will be more affected.

The printer reports that there is a shortage of paper, and if there is paper, it is that the friction of the paper roller decreases and the paper feeding error is reported. Use a wet wipe to wipe the paper roller at the paper inlet of the printer.
